J an 2 00 0 Possible Test of the GUT Relation between M 1 and M 2 in Electron-Photon Scattering

Abstract

We investigate associated production of selectrons and the lightest neutralino (LSP) in the process e−γ −→ χ̃1ẽ−L/R with the selectron subsequently decaying into an electron and the LSP. Total cross sections and various polarization asymmetries are calculated for photons produced by Compton backscattering of a polarized laser beam at an e+e− linear collider… (More)
